Preheat the oven to 180 c / 350°F.
In a large bowl, beat the sugar, margarine & eggs until creamy. Add the food colouring, milk mixed with vinegar + the other tsp of vinegar & set aside.
Into another bowl, sift the dry ingredients.
Slowly add the wet ingredients to the dry, mixing very well to incorporate.
Line bun / cupcake trays with paper cases & carefully fill 1/2 - 3/4 way full. Place in oven.
After 14 minutes, turn the tray around then continue cooking for 4 minutes. Check they're done with a toothpick & allow to cool on thge side.
Once cooled, cut a circular piece out of the top. Fill the hole with whipped or squirty cream. Take the circular piece & cut in half - place on top of the cream to look like a kiss!
